Embodiment 1
[0046] A method for controlling the sewage in rainwater pipelines and sewage pipelines in each area of a drainage system to flow into storage facilities during rainfall. The sewage intercepting pipe connected to the rainwater pipeline, the sewage pipe connected to the sewage pipeline, and the regulation and storage facility; ) is connected to a sewage treatment plant;
[0047] A) When the adjustment and storage facilities do not reach the upper limit of capacity, the flow of the interceptor pipes in each area is not controlled, and when the interception of sewage in a certain area is completed, the interceptor pipes in the corresponding area are closed; and / or
[0048] B) When the adjustment and storage facility reaches the capacity upper limit, adopt the following control method:
[0049] Assuming that the maximum flow of rainwater that can actually be accepted by the end of the system (that is, the end of the regulation and storage facility) is Q, then Q takes the minimum...
Embodiment 2
[0076] A method for controlling the sewage in rainwater pipelines and sewage pipelines in each area of a drainage system to flow into storage facilities during rainfall. The sewage intercepting pipe connected to the rainwater pipeline, the sewage pipe connected to the sewage pipeline, and the regulation and storage facility; ) is connected to a sewage treatment plant;
[0077] The drainage system also includes water conservancy switches arranged on the sewage intercepting pipes in each area;
[0078] The drainage system also includes a control system, the control system includes a device for monitoring rainfall and a control unit connected to the signal; the control unit is connected to the water conservancy switch signal on the intercepting pipe of each area; the monitoring device is used for Monitor the rainfall, generate a rainfall monitoring signal, and send the generated rainfall monitoring signal to the control unit, and the control unit controls the opening of the wa...
Embodiment 3
[0092] This embodiment provides a control system applicable to the method described in Embodiment 1 or Embodiment 2, the control system includes a device for monitoring rainfall and a control unit connected to the signal; The monitoring device is used to monitor the rainfall, generate a rainfall monitoring signal, and send the generated rainfall monitoring signal to the control unit, and the control unit controls the water conservancy on the sewage interceptor in each area according to the received rainfall monitoring signal. the opening of the switch; or,
[0093] The control system includes a device for monitoring time and a control unit connected to the signal; the control unit is connected to the water conservancy switch signal on the intercepting pipe of each area; the monitoring device is used to monitor the time, generate a time monitoring signal, and The generated time monitoring signal is sent to the control unit, and the control unit controls the opening degree of th...
